Chicken egg white coated paper, a sustainable mixed-mode cationic exchange biocomposite to extract antidepressants from saliva samples prior to their determination by direct infusion mass spectrometry

Advances in Sample Preparation
Proteinaceous materials are useful precursors for preparing sustainable and cost-effective sorptive phases. Among them, chicken egg white is an excellent alternative, serving as a source of ovalbumin that can be used as a biosorbent. In this article, the

On-site stir-blade microextraction combined with dual-polarity direct infusion mass spectrometry for analysis of atrazine, daidzein, and genistein in environmental water samples

Green Analytical Chemistry
Integration has emerged as the latter driving force in the evolution of sample preparation, greening analytical measurements through the minimization of steps and their inherent required resources.

Polarization fields in GaN/AlN nanowire heterostructures studied by Off axis holography [PDF]

, 2013
In this work, we present an off-axis holography study of GaN/AlN heterostructured nanowires grown by plasma-assisted molecular-beam epitaxy. We discuss the sample preparation of nanowire samples for electron holography and combine potential profiles ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Sample Preparation — the First Step of Successful Research [PDF]

, 2013
The overall goal of our research project is to study the unfrozen water mass and mobility in frozen soils. Frozen samples of standard clays with different adsorbed cations will be analyzed to determine their surface potential, micro-fabric, and how they ...

Why and When Are Evidence‐Based Interventions Adopted in Paediatric Supportive Care? A Qualitative Exploration of the Determinants of Photobiomodulation Implementation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...

Preferences of Pediatric Patients and Their Caregivers for Chemotherapy‐Induced Nausea and Vomiting Control Endpoints: A Mixed Methods Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Although not always achieved, complete chemotherapy‐induced nausea and vomiting (CINV) control is the conventional goal of CINV prophylaxis. In this two‐center, mixed‐methods study, we sought to understand the preferences of adolescent patients and family caregivers for CINV control endpoints.
